KEY MESSAGES

- Passing cold front will bring through isolated-scattered showers, with some storms possible as well. Coverage will be low, where much of the area should remain dry through the afternoon and evening.

- Temperatures continue trending upwards through Memorial Day Weekend, with above normal temperatures in store for us. Memorial day continues to look beautiful, with mostly clear skies and temperatures in the low-mid 80s.

- Midweek, a system will move in from the south, bringing our next chance for precipitation to parts of the area.

SHORT TERM /THROUGH SUNDAY NIGHT/

Issued at 145 PM CDT Sat May 23 2026

Surface low over Minnesota will continue to track northeast through the afternoon and evening, dragging a weak cold front through the area. Ahead of the front, we have seen moisture increase, which will allow for showers and isolated storms to develop. Overall coverage should be low, as moisture still remains limited out ahead of the front. Aside from lightning and a brief bout of rainfall, we are not expecting much else from this. Much of the area has better chances of remaining dry through the day, owing to isolated-scattered coverage, with best chances for precip south of Interstate 80 with the better moisture. After this front passes, we will see decreasing clouds later tonight. Although, with clouds remaining through much of the night, temperatures are not expected to drop off too much. Temperatures will remain in the mid-upper 50s for most tonight, with a light and variable breeze.

Sunday will be a beautiful day under high pressure. Clear skies will be seen after any remnant AM cloud cover moves east, with temperatures increasing into the low 80s. Otherwise, a light and variable breeze will be felt. Enjoy the beautiful day!

LONG TERM /MONDAY THROUGH FRIDAY/

Issued at 145 PM CDT Sat May 23 2026

The Memorial Day forecast looks to be quite beautiful for the area. Surface high pressure will be passing east of the area, with llvl southwesterly flow increasing overhead. This will result in increasing temperatures, with mid 80s forecast for much of the area. Aside from a breeze and passing clouds, it is geared to be a nice Memorial Day.

Tuesday onward, a cutoff upper low over the southern Plains will slowly lift northward going into Wednesday in response to a building upper ridge over the upper Midwest. This will bring us the next best chance of widespread precipitation, however there remains quite the model spread on amount of available moisture, timing, and the location of strongest forcing. In any case, the latest NBM 72-hr QPF probs for >0.25" remains in the 50-80% range along and south of I- 80, which is similar to the previous forecast package. Once this system eventually dissipates, an Omega block pattern will form over the northern CONUS late in the work week, leading to another dry period and continued above normal temperatures.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1206 PM CDT Sat May 23 2026

VFR conditions will prevail through much, if not all, of the TAF period. A passing cold front will bring the chance (10-30% chance) for isolated-scattered showers/storms. Confidence is low on coverage and impacts at the terminals, prompting PROB30 groups for each. This will move through between 18-00z this afternoon/evening. Brief cig/vis reductions to MVFR will be possible. Otherwise, winds ahead of the front are light and southwesterly around 5-10 KTs, with winds behind west- northwesterly around 5-10 KTs. 00z this evening and beyond, we will see winds go light and variable.
